Practice set 12, read the following metric tape measures and

fill in the blanks. On a metric ruler the smallest division is usually one millimeter and in this first ruler given here, we have a

break so we’re not seeing the beginning of this ruler. The indication of

where we’re at as this 1m, m is the abbreviation that we use

for meter so we’re seeing that this is 1 meter. 1 meter is equivalent to 100 centimeters and that is based on going with the prefix is used in the

metric system. Whe’re given its 1 meter converting it into centimeters will move the decimal place 2 to the

right and to convert into millimeters will move our centimeter value decimal places 1 more to the right, which means we have an equivalent of 1000 millimeters and the reason we’re going in millimeters is because of the fact previously

stated the smallest division on most metric

rulers is one millimeter and if worse here at one meter or equivalent to 1000 millimeters and

the next number indicated is 10 they’re telling

us we have moved 10 millimeters I to the right of that one

meter. So what we’re trying to determine is the length of this line given so

we’re at 1000 meters we’re adding 10-20-30-40-50-60 and a part of the next 10 millimeters onto that and if we’d

look here we’re at still looks like nine past the sixty so we would add on a 69 millimeter length onto our one meter or

the equivalent of 1,000 millimeters for a total of 1069 millimeters for this length. Their asking

us then to convert that into equivalent centimeters and meters and if we go back to the

metric prefix here we have millimeters and we’re going to centimeters from

millimeters, what we have to what we want we’re moving our decimal place 1 to the left so here its understood to be a pass to nine moving it 1 to the left gives us an equivalent 106.9 and if we then take that centimeter and

converted to meters which would be a base unit where

at centi we’ll move it 1 – 2 decimal

places for the base prefix or measurement for length. 2 decimal

places from its current location to the left gives us a value of 1.069 meters. On problem number two all they’re asking us to determine

the length of this line here this ruler also has a break on it and with the

assumption that the smallest division is

millimeters. Looking at the scale the and the values given we have a 700 here which is an indication of 700 millimeters. Going along 700…. 10-20-30-40-50 so on would

bring us up to 800 millimeters with each one of these divisions here showing us there’s ten

divisions 10 millimeters they’re showing us the

value of the increments here. So where are

we with the end up this line we’re at 700… 10-20-30-40- 50 and it looks like 1 millimeter

past 50, so we will and on 51 millimeters on to that value, for a total

751 millimeters, similar to the

previous problems. We’re going to convert that measurement

into centimeters, we’re at millimeters

currently because of the metric ruler shown here moving it to centimeters requires

us to move 1 decimal place to the left because up the fact these prefixes are

right next to one another. The implied decimal place passed the 1 on the right hand side moving it 1 to the left gives us a 75.1 centimeter and if you recall in the previous problem we were at centi and to move to meters then for the final

answer centimeters 1 to decimeters, 2 to the base meter, measurement in lengths gives just 2 decimal places to the left and value of

.751. The third ruler that they

have here again has a break this time we have a 2m which tells us that we have 2 meters and if we convert that into millimeters we’re at a base value with meters. We’re moving at 1-2- 3 places to an equivalent

millimeters, because of the smallest division on

a metric ruler so this would be equivalent to 2000 millimeters and to determine the length

of the line then we are 10-20 and some change. If you

count that we’re at five with this halfway mark, 6-7 places so we would say this is 2000 plus 27 millimeters. adding those together we end up with a

value 2027 millimeters. Converting Milli to Centi is 1 decimal place to the

left 202.7 and if we’re at Centi meters and going to the base with no

prefix on it 2 decimal places to the left gives

us a value if 2.027 meters.
